To all whom it may concern:

Be it known that we, Finnois il. Tor LEY and l/VILLIAM l?. Snins'rnn,citizens of the United States, residing at Brookville, in the county ofFranklin and State of indiana, have invented certain new and usefullmprovements in Sectional Roots for Silos; and we do hereby declare thefollowing` to be a full, clear, and exact description oi the invention,such as will enable others skilled 1n the art to which it appertains tomake and use the same. v

This invention relates to improvements in silos, and more particularlyto theiroot.

l The object ot' the invention is to provide a simple, economical anddurable roof structure, which may be conveniently opened for theintroduction of Inaterial rom the top of the silo.

The invention also comprehends improve# ments in the specific details ofconstruction and arrangement of parts which will be hereinafterdescribed, and particularly pointed out in the claim.

In the drawings: Figure l is a sideeleva-- tion of the upper portion ofa silo with our improved roof in position. Fig. 2 is a plan view with aport-ion removed to better illustrate the ral'ter construction. Fig; 3is a plan view of the roof supporting trarne.

`ig. 4 is a view similar to Figl, but showingthe roof sections thrown'open. Fig. 5 is a detail erspective view of one of thereof sections. 6is a similar view of the roof supporting rame.

The same numerals refer to like parts in all the figures. l indicates acylindrical or .other shaped silo of any approved construction. Mountedontop of the silo l is a frame 2 composed of end and side bars 3 and 4:.Each of the said end and side bars is preferably formed of two boards ofsubstantially the same length and securely spiked together as shown vat5. Each board extends at one end over the adjacent board forming thebar, mortise 6. This construction avoids the necessity of accuratecutting, and also pel'- mits of the use of cheap timber. The noortisedends are fitted i-nto each other and bolts i' fasten them together. Theend and side bars 4 and 5, are seured at' their central portions to thetop edge of the silo l by lag screws 8, and at the corners bybrackets 9.The brackets are each provided at their-upper end with an outwardly bentportion 10,

to provide al formed with an opening to receive one oi' the screws 7.The lower end of the bracket is bent downwardly to engage the outersurface of the silo, and is formed with openings for the passage ofbolts ll. The frame 1s therefore firmly bolted to the silo, and at itscorners it is supported by the angularly disposed brackets, which sup)ort the roof structure about. to be describen.

Firrnly fastened tothe side bars 4-4 are ableframes 13, each comprisinga base oard lll, two upwardly inclined bars 1.5-

l and an intermediate brace har 16,'suitably secured together andprovided with a corrugated sheathing 17. i

The roof proper is composed ,of two or more hinged sections l8-l8 andeach section com rises a :frame 19, and a sheathing 20. Eac i frameconsists of a series otnpwardly inclined transverse braces 20',corresponding to the inclination of the rafters l5, and formed with aseries of mortises 21, in which fit the reduced ends of a series oflongitudinally disposed rafters 22. The upper edge oi each iframe is cutat an angle to form a neat and tight joint when the frames are folded.Over this framework the sheathing 20 is fastened. Each section is hingedto the end bars 3, as indicated at 25, a light distance iromthe lowerouter edge, the overhanging portion 26 of the section serving to shedthe water falling on the roof, and at thesame time acts as anabut-mentto liinit the movement when the'roof sections are thrown openas shown in Fig. 4.

We Vrovide dowel pins 28, at the upper edge ci? one roof section andopenings 29, in the edge of the adjacent section, to forno a. firmjoint, and alsg form a locking connection between the sections when theyare in closed position. Links or'hooks 3l, are pivoted on the inside ofeach section, and en! gage eyes 32 on the gables, whereb to hold thesections in open position when lling the silo from the top.

A. silo roof constructed as above described, will permit ot' the roofsections being thrown. open on their hin es whereby the silo can beconveniently fille from the top, and when said sections are closed theyserve the purpose of an eiiective roof.

`When the sections are thrown sition, as shown in Fig. Il, theoverhanglng portions abut against the silo and prevent said sectionsbeing swung outwardly too far, and therefore act to brace the parte,which in open powith thehooks or links firmly hold the sections in theiropen position.

Having thus described our invention what We claim is The combinationWith a silo, of a horizontelly disposed rectangular-shaped frame uponthe upper edge thereof and having its opposite corners projecting beyondthe circumference of the said silo. onpositely disposed triangular endframes secured to the upper edges of the ends of the rectangular frame,corrugated, Wind-diverting end closures secured to the end frames, withtheir opposite edges projecting beyond the said' triangular frames,hinged roof sections 4secured to the opposite sides of the rectangulartrane and adapted to rest upon the upper converging sides of thetriangular end the roof sections for frames, plates secured to the roof.sections, with the sides overlapping the corrugated end closures, of therectangular frames, hooks carried by the purpose of supportin said roofsections-in open position, and dowels adapted to engage openings formedin the adjacent edges of the roof sections whereby the same will be heldtogether against displacement, substantially as and for the purposes setforth. f

In testimony whereof We aiiX our signatures in presence of twoWitnesses.
